Feasibility analysis of reimplantation after unplanned removal of totally implantable venous access ports

doi:10.11958/20253701

Abstract

Abstract:

Objective To evaluate the feasibility, safety and appropriate patient selection for re-implantation of totally implantable venous access ports (TIVAPs) after unplanned port removal. Methods Clinical data from 10 patients who required unplanned port removal due to TIVAP dysfunction were retrospectively collected to evaluate the technical success rate, postoperative complications and follow-up outcomes of TIVAP reimplantation. Results Ten patients underwent TIVAP re-implantation under digital subtraction angiography (DSA) guidance following unplanned port removal, with a technical success rate of 100%. By the end of follow-up on 30 November 2025, the median follow-up duration was 271 days. Eight patients experienced no further TIVAP-related complications and successfully completed their planned treatments, while two patients required premature port removal due to recurrent pocket rupture with port exposure and persistent wound non-healing, respectively. There were no infection, drug extravasation or other serious adverse events in the intire group. Conclusion TIVAP reimplantation may serve as an effective remedial strategy for selected cases of unplanned port removal, with acceptable safety and economic value.

Key words: totally implantable venous access port, catheter displacement, catheter occlusion, port exposure, port reimplantation
